Energy in Greece
From Wikipedia, the free encyclopedia
Energy in Greece is dominated by fossil gas and oil.[1] Electricity generation is dominated by the one third state owned Public Power Corporation (known mostly by its acronym ΔΕΗ, or in English DEI). In 2009 DEI supplied for 85.6% of all electric energy demand in Greece,[2] while the number fell to 77.3% in 2010.[2] Almost half (48%) of DEI's power output in 2010 was generated using lignite.[2] 12% of Greece's electricity comes from hydroelectric power plants[3] and another 20% from natural gas.[3] Between 2009 and 2010, independent companies' energy production increased by 56%,[2] from 2,709 Gigawatt hour in 2009 to 4,232 GWh in 2010.[2]

In line with the European Commission's Directive on Renewable Energy, Greece aims to get 18% of its overall energy from renewable sources by 2020.[4][needs update]In 2015, according to the independent power transmission operator in Greece (ΑΔΜΗΕ) more than 20% of the electricity in Greece was produced from renewable energy sources and hydroelectric powerplants. This percentage in April reached 50%.[5] The same trend was the case also for 2016.[6]
The contribution of non-hydroelectric renewable energy sources (RES) to the gross final electricity consumption accounted for 24.5% in 2016,[7] while hydroelectric power represented approximately 25% by installed capacity. According to the Greek Electricity Market Operator (LAGIE), the total installed capacity in the Greek interconnected system at the end of 2016 accounted for almost 16,615 MW, including 3,912 MW lignite, 4,658 MW natural gas, 3,173 MW large hydro-power and 4,873 MW RES.[7]
Greece currently does not have any nuclear power plants in operation, however in 2009 the Academy of Athens suggested that research in the possibility of Greek nuclear power plants begin.[8]
As of the 2023 International Energy Agency (IEA) report, Greece has made notable strides in reducing its reliance on lignite for electricity generation. The report highlights a decrease in lignite usage from 60% in 2005 to 10% by 2021. This transition forms a key part of Greece's strategy under the National Energy and Climate Plan and the National Climate Law, aiming for a 55% reduction in greenhouse gas emissions by 2030 and an 80% reduction by 2040. The shift away from lignite is complemented by increased generation from natural gas and renewables like wind and solar photovoltaics, aligning with the country's net-zero emissions goal by 2050.[9]

Perspective
Oil and gas
Greece has 10 million barrels of proved oil reserves as of 1 January 2011.[11] Hellenic Petroleum is the country's largest oil company, followed by Motor Oil Hellas. Greece's oil production stands at 7,946 barrels per day (bbl/d),[11] ranked 90th, while it exports 1,863 bbl/d (57th)[11] and imports 496,600 bbl/d (25th).[11]
In 2011 the Greek government approved the start of oil exploration and drilling in three locations within Greece,[12] with an estimated output of 250 to 300 million barrels over the next 15 to 20 years.[12] The estimated output in Euros of the three deposits is €25 billion over a 15-year period,[12] of which €13–€14 billion will enter state coffers.[12] Greece's dispute with Turkey over the Aegean poses substantial obstacles to oil exploration in the Aegean Sea.
In addition to the above, Greece is also to start oil and gas exploration in other locations in the Ionian Sea as well as the Libyan Sea, within the Greek exclusive economic zone, south of Crete.[13][14] The Ministry of the Environment, Energy and Climate Change announced that there was interest from various countries (including Norway and the United States) in exploration,[14] and the first results regarding the amount of oil and gas in these locations are expected in the summer of 2012.[14]
Gas pipelines include the Gas Interconnector Greece–Bulgaria and the Turkey–Greece pipeline which is a 296 kilometres (184 mi) long natural gas pipeline, which connects Turkish and Greek gas grids completed in 2007.[15]
Coal
Megalopoli Mine is a large lignite and coal mine owned by the Public Power Corporation of Greece. The largest lignite and coal mine in Greece are in the area of Western Macedonia and especially in Ptolemaida. Greece plans to shut down the last coal fired power plant in the country by 2026.[16][17]
Renewable energy

Perspective
Renewable energy in Greece accounted for 29 percent of its electricity from renewable sources in 2021. By 2030, renewables are expected to have a capacity of 28GW, and exceed 61 percent of Greece's electricity consumption.[18] This is a significant increase from 8% of the country's total energy consumption in 2008.[19] By 2022, Greece occasionally reached 100% renewables for a few hours.[20] The target for 2050 is a capacity of 65GW.[21]
Biomass
Regulation Background
EU Renewable Energy Directive 2009/28/EC requires the EU to fulfill at least 20% of its total energy needs with renewable by 2020. This should be achieved through the attainment of individual national targets.[22] EU Commission allocates biomass as the third source of energy within EU after wind.[23] Greek State allocated 350 MW of electricity to biomass - bio-fuels[24]

Solar
Solar insolation in Greece
Solar power in Greece has been driven by a combination of government incentives and equipment cost reductions. The installation boom started in the late 2000s with feed-in tariffs has evolved into a market featuring auctions, power purchase agreements, and self-generation.[30] The country's relatively high level of solar insolation is an advantage boosting the effectiveness of solar panels; within Europe, Greece receives 50% more solar irradiation than Germany.[31]
In 2022, solar power accounted for 12.6% of total electricity generation in Greece, up from 0.3% in 2010 and less than 0.1% in 2000.[32] The national government's 2023 National Energy & Climate Plan anticipates solar PV capacity rising from 4.8 GW in 2022 to 14.1 GW in 2030, and 34.5 GW in 2050.[33]
At the end of 2024, the installed capacity was at 9.6 GW[34], which meant a doubling of the capacity from two years before.See also
